Addition of choice of complementary therapies to usual care for acute low back pain: a randomized controlled trial.

STUDY DESIGN: A randomized controlled trial. OBJECTIVE: To investigate the effectiveness and cost of usual care plus patient choice of acupuncture, chiropractic, or massage therapy (choice) compared with usual care alone in patients with acute low back pain (LBP). SUMMARY OF BACKGROUND DATA: Few studies have evaluated care models with facilitated access to and financial coverage for adjunctive complementary and alternative medicine therapies. METHODS: A total of 444 patients with acute LBP (<21 days) were recruited from 4 clinical sites and randomized into 2 groups: usual care or choice. Outcomes included symptoms (bothersomeness), functional status (Roland), and satisfaction between baseline and 5 weeks, and cost of medical care in the 12 weeks after randomization. RESULTS: After 5 weeks, providing patients with a choice did not yield clinically important reductions in symptoms (median -4, [interquartile range -7, -2] for usual care, and -5 [-7, -3] for choice; P = 0.002) or improvements in functional status (-8 [-13, -2] for usual care, and -9 [-15, -4] for choice; P = 0.15). Although there was a significantly greater satisfaction with care in the choice group, this came at a net increase in costs of 244 dollars per patient. This consisted of a 99 dollars reduction in the average cost to the insurer for medical care but an additional cost of 343 dollars, for an average of 6.0 complementary and alternative medicine treatments per patient. CONCLUSIONS: A model of care that offered access to a choice of complementary and alternative medicine therapies for acute LBP did not result in clinically significant improvements in symptom relief or functional restoration. This model was associated with greater patient satisfaction but increased total costs. Future evaluations of this choice model should focus on patients with chronic conditions (including chronic back pain) for which conventional medical care is often costly and of limited benefit.

Hello, stranger: building a healing narrative that includes everyone.

The authors use the concept of "samaritan medicine" to tie together papers by Klitzman, by Wear and colleagues, and by Branch appearing in this issue of Academic Medicine on the physician-patient relationship. Practicing physicians and trainees alike must confront the challenge of acknowledging and connecting to otherness or difference in patients and in themselves, and practice based in "samaritan medicine" can help to bridge the gaps between self and other. The authors present three vignettes that highlight physicians' and patients' differing perspectives on the stories in which they are mutually involved. The authors then suggest three approaches that operate at the organization as well as the individual level and that speak to establishing and sustaining health-supporting relationships between patients and doctors: video review and replay, Appreciative Inquiry, and self-disclosure. The aim of such approaches is that physicians and physician-trainees be able to ask-and answer-questions about the "narratives" they are enacting, such as "In this story, where am I? Where is the other? Where is the common good? What, then, should I do?" in order that they may develop a robust appreciation of patient interactions and understanding of self that fosters the practice of "samaritan medicine."

The Indiana Chronic Disease Management Program.

The Indiana Chronic Disease Management Program (ICDMP) is intended to improve the quality and cost-effectiveness of care for Medicaid members with congestive heart failure (chronic heart failure), diabetes, asthma, and other conditions. The ICDMP is being assembled by Indiana Medicaid primarily from state and local resources and has seven components: (1) identification of eligible participants to create regional registries, (2) risk stratification of eligible participants, (3) nurse care management for high-risk participants, (4) telephonic intervention for all participants, (5) an Internet-based information system, (6) quality improvement collaboratives for primary care practices, and (7) program evaluation. The evaluation involves a randomized controlled trial in two inner-city group practices, as well as a statewide observational design. This article describes the ICDMP, highlights challenges, and discusses approaches to its evaluation.

Delving below the surface. Understanding how race and ethnicity influence relationships in health care.

There is increasing evidence that racial and ethnic minority patients receive lower quality interpersonal care than white patients. Therapeutic relationships constitute the interpersonal milieu in which patients are diagnosed, given treatment recommendations, and referred for tests, procedures, or care by consultants in the health care system. This paper provides a review and perspective on the literature that explores the role of relationships and social interactions across racial and ethnic differences in health care. First, we examine the social and historical context for examining differences in interpersonal treatment in health care along racial and ethnic lines. Second, we discuss selected studies that examine how race and ethnicity influence clinician-patient relationships. While less is known about how race and ethnicity influence clinician-community, clinician-clinician, and clinician-self relationships, we briefly examine the potential roles of these relationships in overcoming disparities in health care. Finally, we suggest directions for future research on racial and ethnic health care disparities that uses a relationship-centered paradigm.

Not the same everywhere. Patient-centered learning environments at nine medical schools.

BACKGROUND: Learning environments overtly or implicitly address patient-centered values and have been the focus of research for more than 40 years, often in studies about the "hidden curriculum." However, many of these studies occurred at single medical schools and used time-intensive ethnographic methods. This field of inquiry lacks survey methods and information about how learning environments differ across medical schools. OBJECTIVE: To examine patient-centered characteristics of learning environments at 9 U.S. medical schools. DESIGN: Cross-sectional internet-based survey. PARTICIPANTS: Eight-hundred and twenty-three third- and fourth-year medical students in the classes of 2002 and 2003. MEASUREMENTS: We measured the patient-centeredness of learning environments with the Communication, Curriculum, and Culture (C3) Instrument, a 29-item validated measure that characterizes the degree to which a medical school's environment fosters patient-centered care. The C3 Instrument contains 3 content areas (role modeling, students' experiences, and support for students' patient-centered behaviors), and is designed to measure these areas independent of respondents' attitudes about patient-centered care. We also collected demographic and attitudinal information from respondents. RESULTS: The variability of C3 scores across schools in each of the 3 content areas of the instrument was striking and statistically significant (P values ranged from .001 to .004). In addition, the patterns of scores on the 3 content areas differed from school to school. CONCLUSIONS: The 9 schools demonstrated unique and different learning environments both in terms of magnitude and patterns of characteristics. Further multiinstitutional study of hidden curricula is needed to further establish the degree of variability that exists, and to assist educators in making informed choices about how to intervene at their own schools.

A multisite randomized trial of the effects of physician education and organizational change in chronic asthma care: cost-effectiveness analysis of the Pediatric Asthma Care Patient Outcomes Research Team II (PAC-PORT II).

BACKGROUND: A decision to implement innovative disease management interventions in health plans often requires evidence of clinical benefit and financial impact. The Pediatric Asthma Care Patient Outcomes Research Team II trial evaluated 2 asthma care strategies: a peer leader-based physician behavior change intervention (PLE) and a practice-based redesign called the planned asthma care intervention (PACI). OBJECTIVE: To estimate the cost-effectiveness of the interventions. METHODS: This was a 3-arm, cluster randomized trial conducted in 42 primary care practices. A total of 638 children (age range, 3-17 years) with mild to moderate persistent asthma were followed up for 2 years. Practices were randomized to PLE (n = 226), PACI (n = 213), or usual care (n = 199). The primary outcome was symptom-free days (SFDs). Costs included asthma-related health care utilization and intervention costs. RESULTS: Annual costs per patient were as follows: PACI, USD 1292; PLE, USD 504; and usual care, USD 385. The difference in annual SFDs was 6.5 days (95% confidence interval [CI], -3.6 to 16.9 days) for PLE vs usual care and 13.3 days (95% CI, 2.1-24.7 days) for PACI vs usual care. Compared with usual care, the incremental cost-effectiveness ratio was USD 18 per SFD gained for PLE (95% CI, USD 5.21-dominated) and USD 68 per SFD gained for PACI (95% CI, USD 37.36-361.16). CONCLUSIONS: Results of this study show that it is possible to increase SFDs in children and move organizations toward guideline recommendations on asthma control in settings where most children are receiving controller medications at baseline. However, the improvements were realized with an increase in the costs associated with asthma care.

Indiana chronic disease management program risk stratification analysis.

OBJECTIVE: The objective of this study was to compare the ability of risk stratification models derived from administrative data to classify groups of patients for enrollment in a tailored chronic disease management program. SUBJECTS: This study included 19,548 Medicaid patients with chronic heart failure or diabetes in the Indiana Medicaid data warehouse during 2001 and 2002. MEASURES: To predict costs (total claims paid) in FY 2002, we considered candidate predictor variables available in FY 2001, including patient characteristics, the number and type of prescription medications, laboratory tests, pharmacy charges, and utilization of primary, specialty, inpatient, emergency department, nursing home, and home health care. METHODS: We built prospective models to identify patients with different levels of expenditure. Model fit was assessed using R statistics, whereas discrimination was assessed using the weighted kappa statistic, predictive ratios, and the area under the receiver operating characteristic curve. RESULTS: We found a simple least-squares regression model in which logged total charges in FY 2002 were regressed on the log of total charges in FY 2001, the number of prescriptions filled in FY 2001, and the FY 2001 eligibility category, performed as well as more complex models. This simple 3-parameter model had an R of 0.30 and, in terms in classification efficiency, had a sensitivity of 0.57, a specificity of 0.90, an area under the receiver operator curve of 0.80, and a weighted kappa statistic of 0.51. CONCLUSION: This simple model based on readily available administrative data stratified Medicaid members according to predicted future utilization as well as more complicated models.

Practice-level effects of interventions to improve asthma care in primary care settings: the Pediatric Asthma Care Patient Outcomes Research Team.

OBJECTIVE: To assess the practice-level effects of (1) a physician peer leader intervention and (2) peer leaders in combination with the introduction of asthma education nurses to facilitate care improvement. And, to compare findings with previously reported patient-level outcomes of trial enrollees. STUDY SETTING: Data were included on children 5-17 years old with asthma in 40 primary care practices, affiliated with managed health care plans enrolled in the Pediatric Asthma Care Patient Outcomes Research Team (PORT) randomized trial. STUDY DESIGN: Primary care practices were randomly assigned to one of two care improvement arms or to usual care. Automated claims data were analyzed for 12-month periods using a repeated cross-sectional design. The primary outcome was evidence of at least one controller medication dispensed among patients with persistent asthma. Secondary outcomes included controller dispensing among all identified asthmatics, evidence of chronic controller use, and the dispensing of oral steroids. Health service utilization outcomes included numbers of ambulatory visits and hospital-based events. PRINCIPAL FINDINGS: The proportion of children with persistent asthma prescribed controllers increased in all study arms. No effect of the interventions on the proportion receiving controllers was detected (peer leader intervention effect 0.01, 95 percent confidence interval [CI]: -0.07, 0.08; planned care intervention effect -0.03, 95 percent CI: -0.09, 0.02). A statistical trend was seen toward an increased number of oral corticosteroid bursts dispensed in intervention practices. Significant adjusted increases in ambulatory visits of 0.08-0.10 visits per child per year were seen in the first intervention year, but only a statistical trend in these outcomes persisted into the second year of follow-up. No differences in hospital-based events were detected. CONCLUSIONS: This analysis showed a slight increase in ambulatory asthma visits as a result of asthma care improvement interventions, using automated data. The absence of detectable impact on medication use at the practice level differs from the positive intervention effect observed in patient self-reported data from trial enrollees. Analysis of automated data on nonenrollees adds information about practice-level impact of care improvement strategies. Benefits of practice-level interventions may accrue disproportionately to the subgroup of trial enrollees. The effect of such interventions may be less apparent at the level of practices or health plans.

Validity of the HEDIS criteria to identify children with persistent asthma and sustained high utilization.

BACKGROUND: The most widely used performance measure for asthma, the Health Plan Employer Data and Information Set (HEDIS), has been criticized because the delay between classification (year 1) and assessment of medication dispensing (year 2) may produce a "misalignment" and weaken the validity of the measure. OBJECTIVE: To examine whether a previously observed association between the HEDIS performance measure and asthma-related emergency department visits is robust when the period between the classification and outcome assessment is evaluated during a 2-year period as defined. METHODS: Children (N = 2766) aged 3 to 15 years enrolled in 1 of 3 managed care organizations with at least 1 asthma diagnosis listed for a hospitalization, an emergency department visit, or an ambulatory encounter and at least 2 consecutive years of data for analysis from July 1996 through June 1999 were identified. RESULTS: Children did not consistently meet the HEDIS criteria for persistent asthma, and 24% to 28% of children did not requalify in year 2 of observation. Multivariate regression models showed that a protective relationship between controller medication dispensing and asthma-related emergency department visits was no longer seen among children meeting the HEDIS criteria for persistent asthma when the total period of observation is extended to 2 years (odds ratio, 0.7; 95% confidence interval, 0.4-1.2). CONCLUSIONS: Our results suggest that the variable nature of asthma may affect how the HEDIS performance measure should be used for assessing quality of care. The period between identification of the target population and performance assessment should be closely related in time.

A multisite randomized trial of the effects of physician education and organizational change in chronic-asthma care: health outcomes of the Pediatric Asthma Care Patient Outcomes Research Team II Study.

BACKGROUND: Traditional primary care practice change approaches have not led to full implementation of national asthma guidelines. OBJECTIVE: To evaluate the effectiveness of 2 asthma care improvement strategies in primary care. DESIGN: Two-year randomized controlled clinical trial. SETTING: Forty-two primary care pediatric practices affiliated with 4 managed care organizations. PARTICIPANTS: Children aged 3 to 17 years with mild to moderate persistent asthma enrolled in primary care practices affiliated with managed care organizations. INTERVENTIONS: Peer leader education consisted of training 1 physician per practice in asthma guidelines and peer teaching methods. Planned care combined the peer leader program with nurse-mediated organizational change through planned visits with assessments, care planning, and self-management support, in collaboration with physicians. Analyses compared each intervention with usual care. MAIN OUTCOME MEASURES: Annualized asthma symptom days, asthma-specific functional health status (Children's Health Survey for Asthma), and frequency of brief oral steroid courses (bursts). RESULTS: Six hundred thirty-eight children completed baseline evaluations, representing 64% of those screened and eligible. Mean +/- SD age was 9.4 +/- 3.5 years; 60% were boys. Three hundred fifty (55%) were taking controller medication. Mean +/- SD annualized asthma symptom days was 107.4 +/- 122 days. Children in the peer leader arm had 6.5 fewer symptom days per year (95% confidence interval [CI], - 16.9 to 3.6), a nonsignificant difference, but had a 36% (95% CI, 11% to 54%) lower oral steroid burst rate per year compared with children receiving usual care. Children in the planned care arm had 13.3 (95% CI, - 24.7 to -2.1) fewer symptom days annually (-12% from baseline; P =.02) and a 39% (95% CI, 11% to 58%) lower oral steroid burst rate per year relative to usual care. Both interventions showed small, statistically significant effects for 2 of 5 Children's Health Survey for Asthma scales. Planned care subjects had greater controller adherence (parent report) compared with usual care subjects (rate ratio, 1.05 [95% CI, 1.00 to 1.09]). CONCLUSIONS: Planned care (nurse-mediated organizational change plus peer leader education) is an effective model for improving asthma care in the primary care setting. Peer leader education on its own may also serve as a useful model for improving asthma care, although it is less comprehensive and the treatment effect less pronounced.

Differential association of modifiable health behaviors with hot flashes in perimenopausal and postmenopausal women.

OBJECTIVE: To determine the association of modifiable factors, such as smoking, body mass index, and alcohol use, with hot flashes, and to ascertain whether the association with hot flashes varies by menopausal stage. DESIGN: A written survey completed by perimenopausal and postmenopausal women enrolling in a randomized, controlled trial of a menopause risk management program in 1999. Survey items included questions on demographics, health status, and health behaviors. SETTING: A Massachusetts-based health maintenance organization. PATIENTS/PARTICIPANTS: Female members, age 40 to 65, excluding women with chronic conditions precluding study participation, were randomly selected from an automated medical record system. MEASUREMENTS AND MAIN RESULTS: The majority of the 287 postmenopausal and 468 perimenopausal women participating in the study were white, college educated, and nonsmoking. Approximately 30% of both groups reported experiencing hot flashes. Separate multivariable logistic regression models were developed for perimenopausal and postmenopausal women to identify correlates of reporting any versus no hot flashes. After controlling for age, race, oral contraceptive use, hormone replacement therapy use, and depression, correlates of hot flashes in perimenopausal women were body mass index >/=25 kg/m(2) (odds ration [OR], 2.00; 95% confidence interval [CI], 1.28 to 3.12) and alcohol use of 1 to 5 drinks per week (OR, 0.52; 95% CI, 0.31 to 0.86). The only significant correlate of hot flashes in the postmenopausal population was high dietary fat intake (OR, 0.35; 95% CI, 0.15 to 0.81). CONCLUSION: Although study respondents were from similiar sociodemographic groups and received their health care in the same health maintenance organization, modifiable factors associated with hot flashes were different for perimenopausal and postmenopausal women.

Toward an informal curriculum that teaches professionalism. Transforming the social environment of a medical school.

The social environment or "informal" curriculum of a medical school profoundly influences students' values and professional identities. The Indiana University School of Medicine is seeking to foster a social environment that consistently embodies and reinforces the values of its formal competency-based curriculum. Using an appreciative narrative-based approach, we have been encouraging students, residents, and faculty to be more mindful of relationship dynamics throughout the school. As participants discover how much relational capacity already exists and how widespread is the desire for a more collaborative environment, their perceptions of the school seem to shift, evoking behavior change and hopeful expectations for the future.

A controlled study of the effects of state surveillance on indicators of problematic and non-problematic benzodiazepine use in a Medicaid population.

OBJECTIVE: Benzodiazepines (BZs) are safe, effective drugs for treating anxiety, sleep, bipolar, and convulsive disorders, but concern is often expressed about their overuse and potential for abuse. We evaluated the effects of physician surveillance through a Triplicate Prescription Program (TPP) on problematic and non-problematic BZ use. METHOD: This study uses interrupted time series analyses of BZ use in the New York (intervention) and New Jersey (control) Medicaid programs for 12 months before and 24 months after the New York BZ TPP. The regulation required NY physicians to order BZs on triplicate prescription forms with one copy forwarded by pharmacies to a state surveillance unit. Study participants were community-dwelling persons over age 18 continuously enrolled between January 1988 and December 1990 in New York (n = 125,837) or New Jersey Medicaid (n = 139,405). RESULTS: During the baseline year, 20.2% of New York and 19.3% of New Jersey cohort members received at least one BZ prescription. After the TPP, there was a sudden, sustained reduction in BZ use of 54.8% (95% CI = [51.4%, 58.3%]) in New York with no changes in New Jersey. Significantly greater reductions were experienced by young women, and persons living in zip codes that were urban, predominantly Black, or with a high density of poor households. Increases in potential substitute medications were modest. At baseline, nearly 60% of BZ recipients had no evidence of potentially problematic use. Despite a somewhat greater likelihood of discontinuation of BZ therapy among those with potentially problematic use, the largest impact of the TPP was a substantially greater relative reduction in access to BZs among non-problematic users. CONCLUSIONS: State-mandated physician surveillance dramatically reduces BZ use with limited substitution of alternative drugs, lowers rates of possible abuse, but may severely limit non-problematic BZ use.

Patients' perceptions of quality of life after treatment for early prostate cancer.

PURPOSE: Treatment for early prostate cancer produces problematic physical side effects, but prior studies have found little influence on patients' perceived health status. We examined psychosocial outcomes of treatment for early prostate cancer. PATIENTS AND METHODS: Patients with previously treated prostate cancer and a reference group of men with a normal prostate-specific antigen (PSA) level and no history of prostate cancer completed questionnaires. Innovative scales assessed behavioral consequences of urinary dysfunction, sexuality, health worry, PSA concern, perceived cancer control, treatment decision making, decision regret, and cancer-related outlook. Urinary, bowel, and sexual dysfunction were assessed with symptom indexes; health status was assessed by the Physical and Mental Summaries of the Short Form (SF-12) Health Survey. RESULTS: Compared with men without prostate cancer, prostate cancer patients reported greater urinary, bowel, and sexual dysfunction, but similar health status. They reported worse problems of urinary control, sexual intimacy and confidence, and masculinity, and greater PSA concern. Perceptions of cancer control and treatment decisions were positive, but varied by treatment: prostatectomy patients indicated the highest and observation patients indicated the lowest cancer control. Bowel and sexual dysfunction were associated with poorer sexual intimacy, masculinity, and perceived cancer control; masculinity and PSA concern were associated with greater confidence in treatment choice; and diminished sexual intimacy and less interest in PSA were associated with greater regret. CONCLUSION: The lack of change in global measures of health status after treatment for early prostate cancer obscures important influences in men's lives; cancer diagnosis and treatment complications may result in complex outcomes. Aggressive treatment may confer confidence in cancer control, yet be countered by diminished intimate relationships and masculinity, which accompany sexual dysfunction.

The need for an integrated biopsychosocial approach to research on successful aging.

Successful aging is defined not by longevity alone but also by sufficient well-being (in multiple domains) to sustain a capacity for functioning adequately in changing circumstances. The determinants of such well-being and functional status are manifold and include the genetic endowment, physical environment, social environment, population and individual responses to challenges, the occurrence of disease, availability and effectiveness of health care, and personal prosperity. In the face of such complexity, scientific approaches to the phenomena associated with successful aging should be appreciative and wholistic as well as reductionistic. Such a "natural science" of aging will be required to uncover and use information about linear, cause-and-effect phenomena, as well as about higher-order emergent patterns that are of relevance to the health of elderly persons, such as "resilience" and "generativity." Taken as a whole, this multimethod research agenda will truly express an integrated biopsychosocial approach to research on successful aging.

Measuring patients' perceptions of the outcomes of treatment for early prostate cancer.

BACKGROUND: Compared with careful attention to the physical (eg, urinary, bowel, sexual) dysfunction that may follow treatment, little attention has been given to the behavioral, emotional, and interpersonal changes that the diagnosis of early prostate cancer and subsequent physical dysfunction may bring. OBJECTIVE: To construct patient-centered measures of the outcomes of treatment for early prostate cancer. RESEARCH DESIGN: Qualitative study followed by survey of early prostate cancer patients and group of comparable patients with no history of prostate cancer. Analysis of focus groups identified relevant domains of quality of life, which were represented by Likert scale items included in survey questionnaires. Psychometric analyses of survey data defined scales evaluated with respect to internal consistency and validity. RESULTS: Qualitative analysis identified three domains: urinary control, sexuality, and uncertainty about the cancer and its treatment. Psychometric analysis defined 11 scales. Seven were generically relevant to most older men: urinary control (eg, embarrassment with leakage), sexual intimacy (eg, anxiety about completing intercourse), sexual confidence (eg, comfort with sexuality), marital affection (eg, emotional distance from spouse/partner), masculine self esteem (eg, feeling oneself a whole man), health worry (eg, apprehensiveness about health changes), and PSA concern (eg, closely attending to one's PSA). Four scales were specific to the treatment experience: perceived cancer control, quality of treatment decision making, regret of treatment choice, and cancer-related outlook. CONCLUSION: The scales provide definition and metrics for patient-centered research in this area. They complement measures of physical dysfunction and bring into resolution outcomes of treatment that have gone unnoticed in previous studies.
